CVE-2025-23946 is a medium severity vulnerability classified as Cross-site Scripting (XSS) affecting the Enhanced YouTube Shortcode plugin. This vulnerability allows for the improper neutralization of input during web page generation, leading to stored XSS. It affects versions from n/a through 2.0.1. Organizations utilizing this plugin are at risk, and immediate attention is required to mitigate potential threats.
The CVSS score for this vulnerability is 6.5, indicating a medium severity. The attack vector is network-based, with low attack complexity and requiring low privileges. User interaction is necessary, which means that an attacker needs users to engage with malicious content to exploit this vulnerability. Given the potential impact on confidentiality, integrity, and availability, organizations should take this vulnerability seriously.
Currently, no public exploits have been confirmed, and the vulnerability status is deferred. However, organizations should not be complacent and should prioritize patching immediately against this vulnerability to avoid possible exploitation.
Urgency for defenders is high. Even without confirmed exploits, the nature of XSS vulnerabilities means that they can be leveraged in various attack scenarios, potentially leading to unauthorized actions on behalf of the user. Timely remediation is critical to maintaining secure environments.
Vulnerability Details
The vulnerability described in CVE-2025-23946 is classified as Cross-site Scripting (XSS), specifically an improper neutralization of input during web page generation. It affects the Enhanced YouTube Shortcode plugin, versions n/a through 2.0.1. The vulnerability allows stored XSS, which can be exploited to execute arbitrary scripts in the context of the user’s session.
The CVSS score is 6.5, indicating medium severity. The attack vector is network-based, which implies that an attacker can exploit the vulnerability remotely through the internet. The attack complexity is low, requiring minimal effort to exploit, and privileges required for the attack are low. User interaction is needed, as victims must engage with the malicious payload for exploitation to occur.
This vulnerability is classified under CWE-79, which refers to improper neutralization of input during web page generation. Organizations using the Enhanced YouTube Shortcode should take immediate action to mitigate this risk.
Technical Analysis
The root cause of CVE-2025-23946 lies in the failure to properly sanitize user input before rendering it on web pages. This oversight allows attackers to inject malicious scripts, which can be executed in the browsers of users visiting the affected web pages.
The attack vector for this vulnerability is network-based, meaning that it can be exploited over the internet. The complexity for exploitation is low, as it does not require advanced skills or resources, making it accessible for a wide range of attackers. Privileges required to exploit this vulnerability are low, meaning that even non-privileged users can potentially trigger the attack.
User interaction is necessary for this vulnerability to be exploited, as users need to engage with the malicious content. The potential impacts on confidentiality, integrity, and availability are categorized as low, but the ramifications of an XSS attack can still be significant, leading to unauthorized actions being performed on behalf of the user.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-23946 is notable. Organizations that utilize the Enhanced YouTube Shortcode plugin may expose their users to potential XSS attacks, which can lead to unauthorized access or manipulation of user data. This vulnerability highlights the importance of rigorous input validation and sanitization in web applications.
The blast radius for this vulnerability can be significant, especially if exploited in an environment with high user traffic. Attackers may leverage the vulnerability to compromise user accounts, steal sensitive data, or propagate malware. Organizations must recognize that the consequences of not addressing this vulnerability could lead to reputational damage and financial loss.
Given the CVSS score of 6.5 and the current assessment of risk, organizations should prioritize remediation efforts. The vulnerability is classified as medium severity and is a reminder of the ongoing threats posed by XSS vulnerabilities.
